Harrison's H4 T-Shirt

Regular price £20.00 £15.00 Sale

Our unisex John Harrison T-shirt Features an abstract design based on Harrison’s famous H4 marine timekeeper that has been printed on to an olive green crew neck T-shirt; making it the perfect souvenir for a horologist.

The H4 marine timekeeper is John Harrison's prize-winning longitude watch, which he completed in 1759. Harrison had been working on improving watches as a side-line to his development of the much larger H3. In 1753 a pocket watch was made to Harrison's design by watchmaker John Jefferys. This went so well that Harrison began to realise that it pointed to the longitude solution - not in H3 but in smaller watches. Work began on H4 in 1755 and, with its very stable, high frequency balance; it proved to be the successful design, eventually winning the Longitude Prize for him by an Act of Parliament in 1773.

This T-shirt is exclusive to Royal Museums Greenwich and is part of our Longitude & John Harrison collection.
